How's the weather? Can I not add it?

Weather is an uncountable noun. In all usages, most of them need to add the article the in the title, including this example, which is as follows:

The weather gradually cleared up after a heavy rain.

The weather gradually cleared up after a heavy rain.

The weather has been very dry this week.

The weather is very dry this week.

There is only one situation without the addition of the, that is, when there is an adjective in front of the weather, it is described as cold, rainy and hot. . . For example:

I don't like cold weather

I don't like cold weather.

The weather is very good today. We have a good weather today.

It is sunny today.
